The value of the expression when x = 6 is
Answer:
-21.
Step-by-step explanation:
(6)2-7(6)+9
--> 6x2= 12
--> 7x6= 42
Rewrite the expression:
--> 12-42+9
Solve:
--> 12-42= -30
--> -30+7= -21
Answer:
(x -7)²
x = 7
Step-by-step explanation:
Given the quadratic function (polynomial):
x² - 14x + 49 = 0
The first term (x²) and the last term (49) are both perfect squares and the second term is the sum of the product of these two terms (-7 + -7 = -14):
(x - 7)(x - 7) = (x-7)²

Answer:
Constant of proportionality is $6 for one pair and cost of dry cleaning 11 pairs of pants is $66.
Step-by-step explanation:
Dry cleaning fees is directly proportional to the charges of dry cleaning.
Cleaning fee ∝ Pairs of pants
Cleaning fee = k × Pairs of pants
where k is the proportionality constant.
If dry cleaning fee for 3 pairs of pants is $18 then from the equation given above
18 = k ×3
k =
SO the equation will be Cleaning fees = 6×Pairs of pants
For 11 pairs of pants,
Cleaning fees = 6×11 = $66
Therefore, constant of proportionality is $6 for one pair of pants and cost of dry cleaning 11 pairs of pants is $66.
